The specific embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
With reference to accompanying drawing 1; The utility model shown in the accompanying drawing provides a kind of embodiment of Modular LED street lamp, comprises lamp bracket and lamp module, and said lamp bracket comprises power pack 6, connector 5 and end cap 4; The two ends of connector 5 are fixed power source box 6 and end cap 4 respectively; Said lamp module comprises radiator 3, LED module 2 and the lens 1 that interfix, and said LED module 2 is arranged between radiator 3 and the lens 1, and said lamp module is fixed on the said connector 5.
Wherein, the material of said lens 1 is plastics or glass, is convenient to the printing opacity of said LED module 2.
Cancelled the fixed mount of the left and right sides, reduced the light fixture cost, lamp module is fixed on the connector 5; Wherein the top of radiator 3 is fixed on the connector 5; Other parts are exposed in the air, and the profile of radiator 3 is arranged to the shape of intermediate projections, is convenient to the eliminating of rainwater or dust.Radiator 3 is in when heat radiation, can be directly and surrounding air generation convection current, fast heat is distributed.
In the present embodiment, with reference to accompanying drawing 1, said connector 5 shown in the accompanying drawing is dull and stereotyped, and the two ends of said flat board are separately fixed at an end of power pack 6 and end cap 4.
Dull and stereotyped fixing mode is multiple, and it is fixed to come according to operating position and surrounding environment, and among the embodiment, the fixed form of said flat board and power pack 6 and end cap 4 among other embodiment, can adopt buckle connection, riveted joint, welding etc. for being threaded.
In the present embodiment, with reference to accompanying drawing 1, said lamp module shown in the accompanying drawing is a plurality of, is arranged side by side along connector 5, and is fixed on the said connector 5 through being threaded.
On connector 5, be set up in parallel a plurality of screws; On the radiator 3 locating hole is set; Bolt or screw pass locating hole and the screw fixed heat sink 3 on the connector 5 on the radiator 3 on keeper, and wherein its fixed form can adopt other releasable connections, for example buckle connection etc.; Make lamp module removable separately being arranged on to make Modular LED street lamp have commutativity on the locating piece, be convenient for changing and safeguard; The length of locating piece specifically limits according to the lamp module of installing, and expands according to actual needs, and when problem takes place the LED of a lamp module, can directly change the lamp module of damage, and disassembling, assembling and replacing is convenient.
In the present embodiment, be provided with the gap of being convenient to circulation of air between said lamp module and the lamp module.
Between each lamp module, be provided with the gap, air-flow can pass the exchange that cold and hot air is carried out in this gap, forms better cross-ventilation, increases the efficient of heat radiation.
In the present embodiment, with reference to accompanying drawing 1, said radiator 3 shown in the accompanying drawing comprises the heat radiation rack of hollow and is located at heat sink in the said heat radiation rack that said heat sink row side by side is located in the heat radiation rack.
Be arranged on the heat radiation rack in the outside, can effectively cover of the influence of external environment such as rainwater Modular LED street lamp.Heat sink wherein is set up in parallel in heat radiation rack, and it forms a plurality of heat dissipation channels, and air passes this heat dissipation channel, forms with good cross-ventilation, increases the efficient of heat radiation.
Wherein, with reference to accompanying drawing 1, said heat radiation rack shown in the accompanying drawing is provided with the groove of adaptive LED module 2 and lens 1, and LED module 2 is fixed in the said groove with lens 1.
The groove that is fixed on heat radiation rack can prevent the influence of external environments such as rainwater, further, can increase contact area, improves heat radiation.
The material of said radiator 3 is an aluminium, can further increase the radiating effect of whole Modular LED street lamp, and among another embodiment, said radiator 3 adopts the lighter magnesium alloy materials of weight, reduces the overall weight of LED street lamp, makes easier for installation.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
